Atypical Teratoid/Rhabdoid Tumor of Lumbar Spine in an Infant: A Case Report

Atypical teratoid/rhabdoid tumor (AT/RT) of spine usually reported to develop in the brain, while it rarely manifest in the spine. It consists of rhabdoid cells and is highly malignant. AT/RT appears at various sites throughout the body, such as in the central nervous system, liver, kidneys, abdomen, and soft tissues. Among them, spinal AT/RT is rare, and AT/RT of lumbar spine is extremely rare; only a few cases have been reported. We present the case of an AT/RT of lumbar spine in a 16-month-old boy.

Pyomyoma after Uterine Artery Embolization for Postpartum Hemorrhage Misdiagnosed as Uterine Necrosis

A 34-year-old female patient underwent uterine artery embolization (UAE) to control massive postpartum hemorrhage. The interventional radiologist was not informed of the patient's significant history of uterine myoma. Although no significant signs of complications or “red flags” were observed during the procedure, follow-up computed tomography performed four weeks later revealed evidence of a large, globe-like fluid collection with air bubbles in the uterus. The finding and pathology was initially diagnosed as uterine necrosis, which led not to interventional percutaneous drainage; instead, dilation and curettage with resectoscope was performed. The surgical and pathological diagnosis was “expulsion of pyomyoma in the uterine cavity.” Awareness and precise knowledge of imaging findings of pyomyoma and uterine necrosis are important for early diagnosis and treatment of UAE-related complications.
